Description
Technical Field
The invention relates to the technical field of waste treatment, in particular to a heat exchanger for waste treatment, and specifically relates to a high-temperature area heat pipe type heat exchanger special for an urban and rural waste gasification furnace.
Background
Along with the development of social economy and the aggravation of urbanization process, the environment is greatly polluted by municipal wastes (plastics, waste paper, fallen leaves, sawdust, various packaging boxes, beverage bottles, beverage boxes and leftovers), municipal excrement, food and drink garbage, medical garbage, biochemical sludge, industrial coal slime, sludge of an organic matter-rich municipal sewage system, organically processed organic sludge of wood and the like, breeding excrement and breeding sludge in rural areas, breeding dead bodies of sick and livestock, organic matter river mud, plant straws, waste wood and various wastes.
The originally adopted garbage landfill mode leads each big city to be gradually surrounded by garbage, thus polluting atmosphere and underground water, in particular plastics and products thereof. Later, three new problems are discovered after garbage is directly burned, namely, garbage percolate generated by leftovers cannot be treated, and then dioxin generated by burning brings more serious air pollution. And because the water content of the garbage is large, the garbage is difficult to burn completely by burning, and the burning residues still contain a large amount of pollutants, so that the direct discharge brings secondary pollution. The direct incineration of medical waste has greater danger due to incomplete treatment because of various pathogens, chemical agents and the like.
The thermochemical biomass gasification technology is a process of converting biomass into combustible gas by thermochemical reaction at high temperature by using biomass as a raw material and using oxygen (air, oxygen-rich gas or pure oxygen, etc.), water vapor or hydrogen as a gasifying agent. The gasification technology can completely convert low-grade solid biomass into high-grade combustible gas, so that the gasification technology can be widely applied to various fields of industrial and agricultural production, such as centralized gas supply, heat supply, power generation and the like, and the current biomass gasification technology mainly comprises a fixed bed gasification technology, a fluidized bed gasification technology and the like.
The fluidized bed gasification furnace has the advantages of uniform heat and mass transfer, high gasification reaction speed, high carbon conversion rate and easy enlarged design; the disadvantages are high ash content in the combustible gas, complex equipment structure and raw material pulverization and refinement.
Fluidized bed gasification technology is directed to medium and above scale applications, and problems to be solved urgently include:
① tar is still present in the gasified gas, which makes the gasification power generation and gas supply system unable to operate stably for a long time and causes secondary waste water pollution.
② the efficiency of power generation by direct combustion of fluidized bed is only 15% -25%, and the efficiency of power generation by gasification-gas turbine combined cycle power generation (IGCC) can only reach 35%, because the high-temperature crude gas and the waste heat of the generator tail gas are not utilized, the heat efficiency is low, the power generation efficiency is low, and the efficiency of biomass utilization can be improved by more than 60% by adopting the combined cycle power generation and heat supply cogeneration of gasification-gas turbine.
③ it is necessary to develop a gas-type gasification furnace with high gasification efficiency and no tar, to improve the heat value of the gas, and to facilitate the use of IGCC multi-generation heat and power.
④ the adoption of BIGCC technology requires the development of low-heat value gas turbines and high-efficiency gas purification systems with simple structures and low operation cost.
⑤ BIGCC technology needs large-scale development and application, and solves the problem of gasification gas cost.
The urban and rural organic solid waste is gasified by a circulating fluidized bed, carbon particles which are not completely reacted can return to the gasification furnace through the material returning device for further reaction, so that the gasification efficiency is improved, and the heat value of fuel gas can reach 5-8 MJ/m3 (standard state). The material adaptability of the circulating fluidized bed with the bed material is strong, longer straws can be smashed (generally, straws below 5cm can be fully reacted), the bed material can quickly heat the added organic solid waste materials in cities and towns, the gasification reaction time is shortened, and more combustible components are generated. The direct utilization of hot combustion gas can avoid the pollution of tar condensation to pipeline equipment, which is the main development direction of the next urban and rural organic solid waste large-scale complete gasification technology.
Different from urban and rural waste direct-fired boilers, the urban and rural organic solid waste circulating fluidized bed gasification furnace generates combustible gas, the air required by the gasification furnace is preheated, greater risk exists through direct heat exchange with fuel gas, once more solid materials exist in the fuel gas, the heat exchanger is subjected to stronger abrasion, so that gas leakage of a heat exchange wall is caused, explosion danger can be easily caused, and therefore the traditional heat pipe heat exchanger, the fin heat exchanger and the plate heat exchanger have greater explosion danger, even if the wear-resistant coating is added, the wear-resistant time is prolonged, and the danger still exists strongly.
